Abstract. Aerosol acidity is a key parameter in atmospheric aqueous chemistry and strongly influences the interactions of air pollutants ecosystem. The recently proposed multiphase buffer theory provides framework to reconstruct long-term trends spatial variations aerosol pH based on effective acid dissociation constant ammonia (Ka,NH3∗). However, non-ideality droplets major challenge limiting ...

The nonideality of CO2 solutions in ionic liquids and other low volatile solvents, with which CO2 is known to form electron donor-acceptor (EDA) complexes, is here investigated. It is shown that the deviations from the ideality observed are not related with the stability of the EDA complex formed, and inmost cases these deviations are small and dominated by entropic effects. For this reason, wh...

The present contribution analyzes the influence of a type of algebraic nonlinearity in the circuit implementation of the Rossler system, on the nonlinear dynamics of this chaotic generator. The analogue multiplier, imposed by the nonlinearity in the Rossler state equations, is implemented using a bipolar junction transistor Gilbert cell. Its nonlinear input-output characteristic is reviewed, th...

A modification of the extended UNIQUAC model is proposed for the description of the non-ideality of protein solutions. Here, the Staverman–Guggenheim combinatorial contribution used in extended UNIQUAC model is replaced by the Flory–Huggins term to take into account the size differences between the protein and solvent. This new model allows an excellent description of the activity coefficients ...

   Hybrid polyaniline (PANI) based composites incorporating zinc sulfide (ZnS) nanoparticles (NPs) have been synthesized by using chemical oxidation technique. Schottky junction is constructed by depositing Polyaniline-zinc sulfide nanocomposite (PANI-ZnS NCs) on Au electrode. The results were compared with pure polyaniline. The I–V characteristics of the PANI-ZnS NCs hete...

Detection of nuclear radiation such as alpha particles has become an important field of research in recent history due to nuclear threats and accidents. In this context; deoxyribonucleic acid (DNA) acting as an organic semiconducting material could be utilized in a metal/semiconductor Schottky junction for detecting alpha particles. In this work we demonstrate for the first time the effect of a...

Aiming to contribute drug pre-formulation, new eutectic mixtures were developed. Thymol, coumarin, or quaternary ammonium chlorides as excipients, combined with the active pharmaceutical ingredients (APIs) acetylsalicylic acid, acetaminophen, ibuprofen, ketoprofen, lidocaine. Their solid-liquid equilibrium (SLE) binary phase diagrams measured study eventual separation between compounds, prevent...

We perform a spatially resolved simulation study of an AND gate based on DNA strand displacement using several lengths of the toehold and the adjacent domains. DNA strands are modelled using a coarse-grained dynamic bonding model [C. Svaneborg, Comp. Phys. Comm. 183, 1793 (2012)]. We observe a complex transition path from the initial state to the final state of the AND gate. This path is strong...
